fastbanshee8 Posted April 30, 2007 Report Posted April 30, 2007 i was checking every passage there clean in the carb the floats are exactly 21-22mm without the gasketalso needle and seet and very clean??? what should i do about the bowl leaking?? In one of your previous posts, you said fuel was dripping out of one of the hoses, and now you are saying the bowl is leaking. Those are two entirely different problems. Which is it? If it's just fuel leaking around the bowl gasket, then put a new one on. Also, you say the needle, and seat are clean, but that doesn't mean it's not letting a small amount of fuel by. I had a set of carbs, several years back, that were over filling the bowls. I cleaned them, but it didn't help. The float needle, and seat, were junk, so I bought new ones, and the problem was solved. It doesn't take much to mess them up either, and you won't necessarily be able to see it. If the floats are set at the correct height, and the bowl is over filling, to the point that fuel is running out your overflow hose, then it's pretty obvious, that the needle, and seat are bad, and need to be replaced. If this is your problem, then the side with the fuel running out, is running rich, and the other side may be fine, but you cannot get it jetted properly, without fixing the problem. Clean carb parts, don't necessarily mean good carb parts. Quote
RIPRuck Posted April 30, 2007 Report Posted April 30, 2007 Are the slides in the right carbs? Are the bowls on the right carbs? Is the choke tube connected? If its idleing than im sure the choke tube is connected but I would check to make sure the slides are in the correct way with the half moon facing the pods and the bowls are on the correct carb. The bowls are different so make sure! If the bike ran fine before the upgrades than its got to be something not installed right with the carbs because your jetting sounds about right. Whats the gap set to when you did the timing plate? Quote
1966nova Posted April 30, 2007 Author Report Posted April 30, 2007 the gap is 20 thousands , the gas leaks slowly out of the bottom vent hose not the bowl gasket......the slides are in correct also, the choke hose is in correct, im going to run it today with the 30 pilots and the red needles,try to buy some new needle and seats,then see what happens thanks fir all of your advice Quote

I got the same kit from him but only used the needles cause the mains were too small and I was told the pilots were too big. Let me know how those 30's work out with that needle! Quote
1966nova Posted April 30, 2007 Author Report Posted April 30, 2007 i just installed the 30 pilots and red needles seems a little better now i got a new snap-on compression gauge re checked it still-75-80 lbs and i kicked it 6-8 times ????? doesnt sound right would the bike run like that on the low end with low compression???? runs strong on big end a little boggy in 6 gear.... i just several weeks ago put new rings/pistons in and had it checked and honed.... but the compression stayed the same with the old pistons?????? im confused Quote
RIPRuck Posted April 30, 2007 Report Posted April 30, 2007 (edited) Did they bore out the cylinders and were the pistons/rings installed the correct size to match the bore? If your gauge isnt broke and your getting the same compression as you did before the top end work than it sounds like you needed to go up a size! I really hope its just your gauge or something minor. When you ran the compression test did you keep the throttle open? I hear your supposed to as you get a different reading. Edited April 30, 2007 by RIPRuck Quote
1966nova Posted April 30, 2007 Author Report Posted April 30, 2007 ive tried 3 gauges all same reading it was stock piston and ring kit .std and i had it honed... i spoke with jeff he said it has to be the low compreesion so ill sent them to him and have it bored....yes i kicked it wot....... Quote
bigboybanshee Posted April 30, 2007 Report Posted April 30, 2007 doesnt have to be exacly 1/4 that depends on the clip position. why are you f`n with me, all I started this with is mains DONT effect the bottom. go walk into a knife. yea I was born yesterday. I dont know how they work your right! Yes, they would have an effect on the bottom end response. Jetting your carbs pertains to throttle postion, not RPM's. The main jet does in fact start coming into play at 1/4 throttle, may even be a little less, and the needle is what controls how much gas is coming out of the main. The needle doesn't completely plug up the main jet when the throttle is "closed", gas will still flow past it if air is pulling it out. As soon as you hit the throttle, it starts lifting the needle up which sits in the main jet, so yes, zonker is right, the main and needle do have a role in bottom end performance...chill out man :thumbsup: Quote
